How quickly can I get a model into Sefaira?
There are many ways to get a model into Sefaira as quickly as possible. One is to take a screenshot of a 2D plan and trace over it in SketchUp. Below outlines an example of how to do this.
You will see that a much more meticulously drawn geometry will give slightly but not significantly different outputs at the concept stage.
What are the steps?
- Take the pdf (screenshot) of your plan;
- Import it into SketchUp
- Place the image in the SketchUp file
- Scale it correctly
- Now trace over it using the pencil or rectangles - I have used a very rough shape to show how quickly this can be done
- Zone your building roughly
- Now you can remove the png/jpeg that you used and complete the model
- The model requires a few checks before opening in Sefaira - see how here.
- Once it is checked and some glazing added, the model can be pre-checked for energy and daylight - see how here.
- Then upload the model into the Sefaira Web Application using the large blue button - see how here.
A special consideration for multi-storey buildings
- Sefaira looks at a SketchUp models and understands where rooms are located by assessing how the floor is divided.
- In this case, the example model contains interior wall planes. The bottom edge of each interior wall plane helps define the rooms' footprints that Sefaira can understand.
- Now, these interior wall planes also extend to the roof.
- Lets say we wanted to model a three storey building, with different room layouts on each floor, using a single-plane modeling technique. We would need to ensure that the interior walls on the ground floor were not defining room footprints for the floor above.
- We could do this by making the ground floor interior walls slightly shorter than the floor-to-floor height. Or, in an Energy Analysis Only scenario, we could opt to use lines on the floor instead of interior walls to define the room footprints.
- You are now ready to setup your model in the web app. Start by checking out Zoning. See the article on how best to do it here.
